Just got the following on the subject of ethanol in fuel from a Technical Specialist at the AA:
"We are also very concerned about the effects of ethanol. We have
already received many reports of failure of rubber fuel hoses as a
result of using ordinary petrol with only around three per cent ethanol
content.
Last year we assisted a fuel scientist who was preparing a report on the
effects of ethanol, particularly if the UK does adopt the higher blends.
This was a follow-up to the Fuel Quality Consultation. The report
should be published shortly and as soon as it is available I'll send a
copy or a link to the website.
In terms of your own Mini, Burlen Fuel Systems in Wiltshire are aware of
the ethanol issue and have ethanol resistant parts in stock. The
situation with the Golf is less clear, but I am trying to establish
whether you are likely to experience any problems and will let you know
when I send the report."
